    CC can't be negative, so there is something wrong with the FC/CC/TC results. Other than that, things look fairly good. CYA and Salt are both higher than I like to see, but I doubt they are high enough to cause any problems.

    For the cloudy water, I suggest trying to add a little DE to your sand filter. There are instructions on how to do that in Pool School.

    Thanks for the help
    I saw somewhere that CYA should be in the 50-100 range with my SWG.....What range would you suggest?

    Re: Cloudy blue water

    In my Taylor test kit...I subtract FC from TC (2-5) to get CC ....... Would my reading be 3 or -3?
    Seems I forgot a lot from last season

    Re: Cloudy blue water

    For a SWG, I recommend CYA between 70 and 80.

    If you are getting FC of 5 and TC of 2, something has gone wrong. TC has to be higher than or equal to FC. Maybe the TC test is just starting to bleach out. You could try doing the test again with a one to one dilution with chlorine free water.

    FC + CC = TC Looks like your CC (bad stuff) could be 3. I wouldn't swim in it myself.

    "IF" your CC is that high-----shocking will cure it and some good sunshine helps too.

    Susi - if your CC is really 3 you need to shock the pool - you should turn off the SWG and do an overnight FC loss test and see if your FC is holding. If the CC is 3 it probably isn't. Instructions are in Pool School. If you do need to shock - I recommend you drain some of the water out to lower your CYA level down to 60-70 and use liquid chlorine to shock the pool.
